Patented Oct. 16, 1906.

T0 at whom, it may concern:

Be it known that we, THOMAS AKIN DAL- RYMPLE and ROBERT BURNSIDE, Jr, of the city of Montreal, in the Province of Quebec and Dominion of Canada, have invented certain new and useful Improvements in Lubricators, of which the following is a lull, clear, and exact description.

Our invention relates to new and useful improvements in a device for lubricating the cylinders of steam-engines; and the object is to provide a lubricator that will be simple and inexpensive in construction as well as durable and efficient in operation.

A further object is to provide a lubricator that will not overheat the oil nor cross-feed from one cylinder to the other and thatwill be constant and regular in the delivery of the oil.

A still further object is to provide a means for refilling the oil-reservoir without disturbing the regulation of the feed.

The device consists, essentially, of a condenser-globe of the ordinary type, a reser voir beneath it in which the lubricating-oil is adapted to float on the water of condensation at a sufiicient height to allow it to flow by gravity through a suitable pipe into one or more sight-feed regulators filled with water,

through which the oil rises and passes into the discharge-pipes.

elevation of the same.

5 isa In the drawings which illustrate our invention, and in which similar numerals of reference refer to similar parts throughout, Figure 1 is a front elevation of the lubricator, partly in vertical section. Fig. 2 is a rear Fig. 3 is a side elevation and shows one of the sight-feed units vertically sectioned through the center. Fig. 4is a plan view of the lubricator. Fig. plan view of one of the sight-feed glasses and shows the packing and gland in section. Fig. 6 is a vertical section of the bafiie-plate.

Referring to the parts, 1 designates the threaded neck, through which steam enters the condenser-globe 2.

3 is a valve leading from the condenser into a pipe 4, which extends to the bottom of the reservoir 5. The lubricating-oil fills the reservoir above the level of the water of condensation and is thus enabled to enter the open top of the oil-pipe 6. Passing down this pipe the oil enters the header 7, from which when the regulating valves are opened it is forced through the ducts 9 in the shouldered nozzles 10, screwed into the top of the'header 7. The oil rises in drops through the water which fills the cells 11. Each of the nozzles is placed in a separate cell 11, walled in by the sides of the chamber 12 and the vertical diaphragms 13. These diaphragms 13 are intersected by across-diaphragm 14, which is screw-threaded to receive the conical baffle-plates 15, provided at their ap'ces with apertures 16 for the escape of the oil.

The threaded neck 1 is provided with a gland 17, having an equalizing-pipe 18 leading therethrough. The lower extremity of the pipe 18 terminates in a gland 19, mounted on the top of a hollow vertical rib 20, which opens at its lower end into a transverse water-header 21. Passages 22 lead from the header 21 into each of the cells 11 above the cross-diaphragm 14, thus equalizing the pressure in all of the cells. Steam is condensed in thepipe 18, and the water of condensation enters the cells 11 above the diaphragm 14 and penetrates into the lower portion through the orifices 23 in the baffleplates 15. It will thus be seen that the cells 11 are filled with water. The drops of oil rising to the surface of the water pass through the apertures 16 in the baffle plates and thence into the discharge-pipes 24, 'where vaporization takes place and the oil is forced into the engine-cylinders.

The reservoir 5 is provided at the bottom with a blow-oil cook 25, and each of the cells 11 is provided with similar cocks 26 for the purpose of cleaning the lubricator. Each of the cells 11 is further provided at the top with a plug 27, having a square depression 28 therein adapted to coact with an internal wrench. A cone-seated plug 29 screws into an aperture in the top of the member 5 for the purpose of filling the reservoir with oil. The reservoir is also provided with an attaching-lug 30, an internal annular strengtheningrib 31, and a heavy threaded boss'32, into which the cell-chamber 12 screws. The regulator-valves are of the ordinary needle type. Each of the cells 11 is provided at both front and back withlglasses 33, which are shaped substantially as shown in Fig. 5. The annular collar 84 forms an abutment for the packing-rings 35. Between the outer packingring and the internal nut 37 a washer 36 is interposed. The nuts 37 are hollow and are provided with slots 38, adapting the nut to be tightened with a screwdriver.

' It will be seen that, the chamber 12 is provided with three separate cells, which may discharge oil into the high and low pressure cylinders and the air-pump of an engine or into the cylinders of a triple-expansion engine. It will be obvious, however, that these cells may be multipled to suit the requirements of any type of engine. As the chamber is separated from the body of the reservoir, the oil is kept comparatively cool and flows in a constant and regular manner. The equalizing of the pressure by means of the pipe 18 also assists in maintaining a constant flow of oil. As the cells are completely separated by the vertical partitions 13, no crossfeeding occurs from one chamberto the other. The oil-chamber may be easily refilled at any time by closing up the valve 3 and emptying the water from the reservoir through the blow-off cook 25, the construction of the baffle-plate 15 being such as to prevent the interference of any back pressure.

The operation of the device will be obvious from the foregoing description, and its many advantages will be apparent to those skilled in the use of lubricators.

It willthus be seen that we have provided a lubricator which is simple, compact, and inexpensive in construction and which is efficient and reliable in operation, especially on locomotive-engines. It may, however, be used with equal advantage on stationary or marine engines.

Having thus described. our invention, so that the same may be readily understood by those skilled in the art to which it appertains, what we claim, and desire to secure by Letters Patent, is-
